Electric fan install help.

I saw this controller on another thread and ordered one.

I wanted one the was sealed and could be mounted under the hood rather than having to run wires all the way inside the pass compartment. With the Dakota controller I would have all that wiring because they don't recommend mounting in the engine bay, I would have to buy another $30 relay and another $30 temp sender. So Dakota $110, extra wiring and connectors $15, extra relay $30, temp sensor $30, total $180.00 and two year warranty.
The Entropy controller= Waterproof, everything included, lifetime warranty + $150.
